Why is that widescreen DVDs of older movies (about 10 or more years old) do not display correctly ??? For instance, I just watched "Crimson Tide" and I needed to place my Sony widescreen TV in "Zoom" mode for it to properly display a 2.35:1 format. If I was to watch in "Full" mode, the image would be stretched and un-naturally short. (My Denon DVD1600 is properly set for a 16:9 widescreen TV). DVDs of newer movies always display in the correct widescreen format with the TV in "Full" mode. My worst experience was watching "The Great Escape" recently. Even with the TV in "Zoom" mode, I was getting a stretched picture... it looked to be about 3.0:1 !!! Is there something wrong with my equipment or is this problem just related to how older movies have been transferred to DVD ???
